    <h2><span style="font-size: 1.5em;">环境：</span></h2>
<p>　　oracle11g + Hibernate</p>
<p>&nbsp;</p>
<h2>错误分析：</h2>
<p>　　网查，这是oracle 11g在clob字段中的一个bug，oracle在insert语句发生时，会默认将entity中所有属性按照首字母排序，clob字段如果首字母是aclob、bclob、clob等，这种情况恰好会排在前面，就可能会出现此异常。</p>
<p>&nbsp;</p>
<h2>解决的方法：</h2>
<p>　　给entity中clob字段属性前加比较靠后的字母，例如zclob。</p>
